BEST MODE

Exemplary embodiments of the present invention are described hereafter in detail with reference to the accompanying drawings.

Common terms that are generally used now were selected for terminologies used herein were selected, but some of them were freely selected by the applicant(s) is specific cases and the meanings were described in detail at the corresponding part in these cases, so it should be understood that the present invention should be construed on the basis of no the name of terms, but the meanings of the terms. Further, technologies well known in the art and not directly relevant to the present invention are not described in the following description of embodiments. This is for clearly communicating the subject of the present invention by omitting unnecessary description.

FIG. 1 is a block diagram illustrating the configuration of a system for providing a public service using an autonomous car according to the present invention.

The system for providing a public service using an autonomous car according to the present invention, as shown in FIG. 1, includes an autonomous smart car 100, an autonomous smart car managing server 200, a public agency server 300, and a missing person information server 400.

The autonomous smart car 100 automatically drives to a destination without a driver when the destination is set, stores images that are input through cameras on the autonomous smart car 100 together with location information and weather information, recognizes faces from the input or stored images, wirelessly transmits information about corresponding face to one of receiving parts, that is, the autonomous smart car managing server 200, the public agency server 300, and missing person information server 400 when the face is that is a missing person, a suspect, or a wanted person, and wirelessly transmits image data, which has been requested by the autonomous smart car managing server 200 or the public agency server 300, of stored image data to the receiving part.

The autonomous smart car 100 includes a black box unit 110, a facial recognizing-processing unit 120, a communication unit 130, an image output unit 140, an autonomous driving unit 150, an encryption unit 160, and a control unit 170.

The black box unit 110 takes and stores images of the surrounding of the autonomous smart car 100. In general, the black box unit 110 stores images and sounds inside and outside a vehicle when the vehicle is being driven or stopped, but further has a function of extracting persons in the present invention. The black box unit 110 of the present invention includes a first camera unit 111, a first memory unit 112, and a person extraction unit 113.

The first camera unit 111 of the black box unit 110 takes images of the inside and outside of the car.

The first memory unit 112 stores images and sounds taken by the first camera unit 111.

The person extraction unit 113 extracts person information from the images of the outside of the car taken by the first camera unit 111. In order to extract the person information, it is possible to use a method of extracting persons by recognizing faces through a smartphone etc., or of detecting movement. The method of detecting movement can provide intellectual characteristics such as detecting, tracing, classifying, recognizing, and integrating movement and analyzing behaviors with the recent development of the imaging technology, image tracing is performed by a series of calculation modules, and the modules respectively perform functions of locating objects (persons and things), recognizing objects, and tracing objects. For example, an Active Shape Model (ASM)-based tracing algorithm models object shapes and matches them to combinations of information about repeatable movement and coarse-to-fine estimation using a combination with a Kalman filter provides a stronger result, and a feature-based shape tracing method called Non-Prior Training Active Feature model (NPTAFM) is provided in order to reduce load in calculation. Such feature-based object modeling can trace an object using considerably less features in comparison to existing shape-based modeling requiring the entire shape.

The facial recognizing-processing unit 120 includes a second camera unit 121, a facial recognition unit 122, a second memory unit 123, and a facial comparison unit 124.

The second camera unit 121 takes image of the outside of the car.

The facial recognition unit 122 makes facial information by recognizing the faces of persons extracted by the person extraction unit 113 of the black box unit 110 or the faces of persons from images taken by the second camera unit 121.

The second memory unit 123 stores facial information of missing persons, suspects, and wanted persons from one of the autonomous smart car managing server 200, the public agency server 300, and the missing person information server 400, and updates the information at a set period.

The facial comparison unit 124 detects missing persons, suspects, and wanted persons by comparing the facial recognition data made by the facial recognition unit 122 with the facial information stored in the second memory unit 123.

The facial recognizing-processing unit 120 is provided to take images of sidewalks for pedestrians under the assumption that the black box unit 110 takes images of the front and rear areas of the car. Obviously, when the black box unit 110 takes images of the entire surrounding of the car, there may be no need for the second camera unit 121.

The communication unit 120 performs wireless communication with one or more of the autonomous smart car managing server 200, the public agency server 300, and the missing person information server 400 outside the autonomous smart car 100.

The image output unit 140 outputs various images and displays corresponding information when a missing person, a suspect, or a wanted person is found. The image output unit can display the faces of missing persons, suspects, or wanted persons, the name of missing persons and the name and contact addresses of guardians or displays contact address information for reporting wanted persons or suspects so that a user of the autonomous smart car 100 can take the follow-up measures (for example, meeting or reporting a missing person).

The autonomous driving unit 150, which is provided for autonomously driving the autonomous smart car 100, may include a location information receiving unit 151, a traffic information receiving unit 152, and an autonomous driving control unit 153.

The location information receiving unit 151 receives the current location information of the car. For example, it receives GPS information.

The traffic information receiving unit 152 receives traffic information to the destination while the autonomous smart car 100 is driven.

The autonomous driving control unit 153, which enables the location information receiving unit 151 to receive the current location of the car and the autonomous smart car 100 to automatically drive to the destination, controls the steering system, brake system, acceleration system, transmission etc. of the car.

The encryption unit 160 decodes received facial information or encodes and transmits facial information or image information of a crime scene to be transmitted outside.

The control unit 170 controls the autonomous smart car 100 and receives facial information from the outside through the communication unit 130, or controls the communication unit 130 to transmit a face information to the outside when a matched face is recognized by the facial recognizing-processing unit 120. Further, discrimination information that is set in advance is stored to discriminate requested information in order to transmit requested information only for rightful requests. This information may be set in advance between the autonomous smart car 100 and the autonomous smart car managing server 200, the public agency server 300, and the missing person information server 400.

The autonomous smart car managing server 200 manages the autonomous smart car 100, transmits the faces of missing persons or facial information of suspects or wanted persons to the autonomous smart car 100. Further, when receiving matched facial information from the autonomous smart car 100, the autonomous smart car managing server 200 transmit the facial information to the public agency server 300 or the missing person information server 400 that needs the facial information, depending on whether the facial information is matched with a missing person, a suspect, or a wanted person. When image information of a crime scene including time and location is requested from the public agency server 300, the autonomous smart car managing server 200 requests an image with identification information set in advance to autonomous smart cars that applied for a public service of autonomous smart cars 100.

To this end, there may be actually problematic factors when the autonomous smart car managing server 200 manages all autonomous smart cars, so it can request image information including time and location requested from the public agency server 300 to autonomous smart cars that applied for public service. It may be possible to request the information to all members of autonomous smart cars or may be possible to selectively request the information by referring to corresponding location and time to autonomous smart cars that agreed with collection of date and location information.

The public agency server 300 may be a server of a police agency or a fire station etc. When the public agency server 300 is the server of a police agency, the server requests images of an area where a missing person, a suspect, a wanted person, or a criminal (a hit-and-run driver, a robber, or a thief) was found, including information about the area and time, to the autonomous smart car managing server 200. When the public agency server is the server of a fire station and the reason of ignition including a fire is unclear, the server requests images of a corresponding area, including information about the area and time, to the autonomous smart car managing server 200.

The missing person information server 400 is a server storing information about missing persons to find missing persons and the mission person information may be facial information, name information, age information, contact address information about the missing person clothing colors worn when gone missing, missing place information, etc. The missing person information server 400 transmits pictures of the faces of missing persons to the autonomous smart car managing server 200.

FIG. 2 is a block diagram showing in detail the configuration of an autonomous smart car managing server shown in FIG. 1.

The autonomous smart car managing server 200, as shown in FIG. 2, includes a communication unit 210, an autonomous smart car DB 220, a public service smart car DB 230, a facial DB 240, a public agency DB 250, an autonomous smart car image DB 260, and a control unit 270.

The communication unit 210 communicates with the autonomous smart car 100, the public agency server 300, and the missing person information server 400 through a communication network 500. The communication network 500 is a wire/wireless communication network.

The autonomous smart car DB 220 stores user information (name, contact address, etc.) of the driver of the autonomous smart car 100 and car information (model name, manufacturing year, etc. of a car).

The public service smart car DB 230 stores information about autonomous smart cars registered on the public service of autonomous smart cars 100. As the information about autonomous smart cars registered on the public service, not only the user information (name, contact address, etc.) and car information (model name, manufacturing year, etc. of a car), but individual identification information set for autonomous smart vehicles 100 to determine whether requested information is rightful information when image data stored in the black box unit 110 or the first memory unit 112 of the facial recognition unit 120 is requested for the autonomous smart car 100 are stored. Further, the driving information of cars registered on the public service, that is, the movement path information for each time unit is stored. The movement path information for each time unit is used later to request images of a crime scene.

The facial DB 240 stores facial information that is transmitted among the autonomous smart car 100, the public agency server 300, and the missing person information server 400. Further, for a missing person, information of the name of the missing person and the name and address of a guardian may be stored together.

The public agency DB 250 stores information about public agencies such as a police agency and a fire station and the organizations that find missing persons. The information about public agency may be the contact address information of police stands, police stations, and fire stations around autonomous cars. The telephone number information of organizations that find missing persons may also be included.

The autonomous smart car image DB 260 stores the images transmitted from autonomous smart cars 100 for each car, date, and location. The images are stored in a database for a predetermined period in accordance with the sizes. The memory size of the first memory unit 112 of the black box unit 110 or the second memory 123 of the facial recognizing-processing unit 120 in an autonomous smart car is deleted in a FIFO (First In First Out) method, so images transmitted from autonomous smart cars are backed up for a predetermined time, depending on the memory sizes of autonomous smart cars.

The control unit 270 controls the autonomous smart car managing server 200.

FIG. 3 is a flowchart illustrating a public service method using an autonomous car according to the present invention.

The public service method using an autonomous car according to the present invention, as shown in FIG. 3, registers a public autonomous smart car (S100). The public autonomous smart car is an autonomous smart car that is set to transmit a crime scene image when recognizing the face of a missing person, a suspect, or a wanted person from images taken by its own black box camera 111 or a separate second camera 121 or when receiving a rightful request for the crime scene image, of autonomous smart cars that can automatically drive without a driver.

The autonomous smart car managing server 200 that manages the public autonomous smart car downloads facial information to the facial DB 240 from the public agency server 300 and the missing person information server 400, and periodically updates the facial information (S110). The autonomous smart car managing server 200 transmits facial information to the public autonomous smart car. Further, the public autonomous smart car stores the facial information in the second memory unit 124.

Then, the public autonomous smart car takes images using the first and second camera units 111 and 121 and stores the images (S120). Time information and location information are stored together with corresponding images. While images are taken, the person extraction unit 113 of the public autonomous smart car extracts persons from the images, the facial recognition unit 122 recognizes the faces of the extracted persons, and the facial comparison unit 124 compares the recognized faces with the facial information stored in the second memory 123.

The control unit 160 of the public autonomous smart car determines whether an event has occurred (S130).

The event occurs when a surrounding image is requested through the public agency server 300 or the autonomous smart car managing server 200 and a same person is detected as the result of recognizing faces from the images taken by the first and second camera units 111 and 112 of the autonomous smart car 100.

When a surrounding image is requested through public agency server 300 or the autonomous smart car managing server 200, image data corresponding to the corresponding data and time is extracted (S140). The image data may correspond to the image at the current location of the autonomous smart car 100 or a past image obtained by referring to the driving record of the autonomous smart car stored in the public service smart car DB 230 of the autonomous smart car managing server 200. Obviously, image data corresponding to the date and time requested from the public agency server exists in the autonomous smart car image DB 230 of the autonomous smart car managing server 200, the image data is not requested for the public autonomous smart car.

The autonomous smart car 100 wirelessly transmits the extracted image data to the public agency server 300 or the autonomous smart car managing server 200 that is the receiving part that requested the image data.

When the even is facial recognition by the facial recognizing-processing unit 120, facial recognition information is output to the image output unit (S160). In this case, for a missing person, the information (name, contact address, etc.) of a guardian of the missing person is output together with matched information. For a suspect, the information about police stands and police stations around the autonomous smart can may also be output.

Accordingly, if there is a user in the autonomous smart car, he/she can take follow-up measures in person. In particular, for a suspect or a wanted person, the user can report to the police etc., and for a missing person, the user can try to talk with the missing person or may contact the guardian if the missing person is a dotard or a child.

Further, facial recognition information and information of date, time, and location are transmitted to the autonomous smart car managing server 200, the public agency server 300, and the missing person information server 400.

Meanwhile, when the autonomous smart car 100 is requested to trace a facial recognition target (object) from a user of an autonomous smart car, it automatically drives and traces the object and transmits location and image information to the autonomous smart car managing server 200, the public agency server 300, and the missing person information server 400 (S190). This tracing is performed until a tracing end instruction is input (S200).

The present invention was described with reference to the accompanying drawings, but it is only an embodiment of various embodiments including the subject of the present invention on the purpose of allowing those skilled in the art to easily accomplish the present invention, and the present invention is not limited to the embodiment described above. Accordingly, the protective range of the present invention should be construed on the basis of the following claims and all technical spirits within an equivalent range through change, replacement, and modification in the range of the scope of the present invention will be included in the range of the right of the present invention. Further, some of the components shown in the drawings may be exaggerated or contracted for clear description.
